2 Claims. (Cl. 20G- 59) This invention relates to paper roll protectorsand more particularly to a protective pad or cushion for an end of aroll of paper, such as a roll of newsprint paper.

It is among the objects of the invention to provide a paper rollprotector in the form of a Hat pad or cushion of resilient material,such as solid or expanded rubber,

which may be placed over one end of a heavy roll of paper, such as aroll of newsprint paper, in covering relationship to the correspondingend of the paper roll so that the roll can be placed on the endprotected by the pad or cushion and supported or transported on such endwithout damage to the paper at the protected end of the roll; which canbe enclosed in the paper wrapping at the corresponding end of the paperroll and requires only an insignicant amount of additional time andlabor for its inclusion in the roll wrapping; which is of light weightand easy to handle and can be returned to the paper manufacturer alongwith the emptied roll cores so that it can be reused a large number oftimes; and which is simple and durable in construction, economical tomanufacture, and effective and ecient in use.

Other objects and advantages will become apparent from a considerationof the following description and the appended claims in conjunction withthe accompanying drawing, wherein:

Figure 1 is a perspective view of a group of heavy paper rolls, such asrolls of newsprint paper, disposed in upright position with one end ofeach roll resting on a oor;

Figure 2 is a fragmentary cross sectional View on an enlarged scale onthe line 2 2 of Figure 1; and

Figure 3 is a perspective View of a paper roll protector illustrative ofthe invention.

With continued reference to the drawing, the numeral 10 generallyindicates a heavy roll of paper, such as a roll of newsprint paper. Asis well known, rolls of newsprint paper are heavy and bulky anddifficult to handle and are usually placed on end during transportationor storage since, because of their length and cylindrical shape, a greatdeal of space would be wasted if they were placed on their sides andthere would also be a tendency for the rolls to roll along the floor onwhich they were supported with consequent danger to persons working nearor with the rolls.

When the rolls are placed on end, as illustrated in Figure l, forconvenience and safety in handling, the edge of the newsprint paper atthe bottom end of the roll is frequently damaged by being wrinkled, bentor torn and, in such a case, a strip of the entire piece of newsprintpaper may have to be removed along one edge of the paper in order tosalvage the remainder of the paper, resulting in an expensive waste ofpaper and in inconvenience in utilizing the ngrrower length of paper.This waste of newsprint paper, although amounting to large sums of moneyevery year in this country alone, has heretofore been consideredunavoidable and an investigation of the paper manufacturing and printingindustries` has disclosed no successful attempt toward eliminating it.

Each paper roll 10, as illustrated in Figure 2, includes a tubular core11 of cylindrical shape formed of a suitable rigid material, such aswood, compressed ber or laminated paper, a body 12 of newsprint paperwound on to the core 11 to provide a roll of cylindrical shape and of apredetermined length and diameter and a wrapping 13 of tough, heavypaper, such as kraft paper, extending around and over the ends of theroll. The portion 13 of the wrapping extending over the ends of the rollis centrally apertured and folded inwardly of the adjacent end of thetubular core 11 to provide openings in the wrapping registering with thebore of the tubular core for the insertion of the usual appliances intothe ends of the core for lifting and moving the paper rolls andsupporting them in position for the paper to be wound oi of the roll.

In accordance with the present invention, a fiat pad or cushion 15 ofresiliently elastic material, such as a solid body of soft rubber or abody of expanded mbber is placed over one end of the roll of paper incovering relationship to the end of the body 12 of newsprint paperbefore the wrapping 13 is applied to the roll or, at least, before thewrapping of the roll is completed.

This pad or cushion 15 is a flat body of circular shape havingsubstantially parallel major surfaces and has a diameter substantiallyequal to the diameter of the body 12 of newsprint paper wound on thecore 11. At its center the cushion is provided with a circular aperture16 of substantially the same diameter as the diameter of the bore of thetubular core 11 of the roll and this aperture registers with thecorresponding end of the bore in the tubular core.

In applying the protector to the end of the paper roll, before theportion 13' of the wrapping 13 is placed over the corresponding end ofthe roll, the protected pad or cushion 15 is placed in coveringrelationship to the end of the paper roll and the portion 13 of thewrapping is then placed over the outer side of this pad or cushion tosecure the protector in position against the corresponding end of theroll.

If desired, the end portion of the rst wrapping may be placed over theselected end of the paper roll, the protective pad 15 placed against theouter side of this end portion of the wrapping and an outer wrapping maybe then secured to the first wrapping and over the side of theprotective pad remote from the end of the roll to secure the pad inproper position to protect the adjacent end of the paper roll.

With the protective pad or cushion 15 in place, if a paper roll istilted or otherwise moved so that its weight is unevenly distributedover its bottom end, the elastic material of the protective pad orcushion will be cornpressed at the location of the greatestconcentration of weight and will tend to distribute this concentratedWeight over a sufficient area of the end surface of the roll to avoid tdamage to the paper of the roll. After a roll has been unwrapped at theprinting plant using the paper, it is customary to return the tubularcore on which the rolls are wound to the paper manufacturer for reuse.The protective pad or cushion 15 of the present invention can be easilyreturned to the manufacturer along with the empty cores so that theseprotectors can also be reused a large number of times making the expenseincident to their provision substantially insignificant.

The invention may be embodied in other specific forms without departingfrom the spirit or essential characteristics thereof. The presentembodimentV is, therefore' to be considered in all respects asillustrativeV and. not restrictive, the scope of the invention beingindicated by thel appended claims rather than by the foregoingdescription, and. all changes which come withinv the meaning and rangeof equivalency of the claims are, therefore, intended to be embracedtherein.

What is claimed is:

1. In combination with a rigid core, a sheet of newsprint paper tightlywound about said core to form a roll, and a heavy paper wrappingextending about and over the ends of said roll, said roll being adaptedto be stored by standing it upon one end thereof, of a flat padinterposed between the heavy paper wrapping extending over the one endof said roll on which the latter is stood for storage and the last-namedone end of said roll and abutting against said one roll end and retainedin the abutting position against said one end of said roll solely by theheavy paper wrapping extending over the aforementioned roll end, saidpad being fabricated of resilient material and being conformably shapedto tit said one end of said roll.

2. In combination with a rigid core having a bore extending axiallytherethrough, a sheet of newsprint paper tightly wound about said coreto form a roll, and a heavy paper wrapping extending about and over theends of said roll, each of the portions of the heavy paper wrappingextending over the ends of said roll having an opening registering withthe adjacent bore end of said core, said roll being adapted to be storedby standing it upon one end thereof, of a at pad interposed between theheavy paper Wrapping extending over the one end of said roll on whichthe latter is stood for storage and the lastnamed one end of said rolland abutting against said one roll end and retained in the abuttingposition against said one end of said roll solely by the heavy paperwrapping extending over the aforementioned roll end, there being anaperture in said pad registering with the opening in the portion of t'neheavy paper wrapping extending over said one roll end, said pad beingfabricated of resilient material and being conformably shaped to t saidone end of said roll.
